Abstract: A road map display device including a road map information memory for memorizing road map data on a two-dimensional coordinate and a detection device for detecting a present position and a travel direction of an automotive vehicle, wherein the two-dimensional coordinate of the road map data is read out from the information memory in accordance with the present position and travel direction of the vehicle detected by the detection device and displayed in the form of a plane view on a screen of a display unit. In the road map display device, trapezoid conversion parameters are determined on a basis of a conversion formula for converting the two-dimensional coordinate of the road map to a trapezoid coordinate for display of a perspective view in such a manner that an upper side of a square two-dimensional coordinate is contracted relatively to a lower side of the two-dimensional coordinate, and the road map data included in a reverse trapezoid coordinate defined by a reverse conversion formula of the conversion formula are read out from the road map information memory and introduced into a trapezoid coordinate defined by the trapezoid conversion parameters such that the road map data are displayed in the form of a perspective view on the screen of the display unit.

Abstract: A navigation system for use in a vehicle including a route-calculating section and a route guide control section. The route-calculating section searches for an optimum route according to conditions set for the search. The guide control section provides displays necessary to guide the driver of the vehicle, and guides the driver by speech. This guide control has a landmark name-setting section which sets the names of landmarks according to information about the landmarks, the information retrieved from a guidance information storage section according to information about the present position from a present position-determining section. A display section displays a whole route map indicating the selected route according to instructions from the route guidance control section. At the same time, the names of the landmarks are presented on the display section. When the navigation system guides the driver to a destination via a tollway such as a toll highway, the name of an entry/exit interchange connecting to the highway is displayed. This permits the driver to take a familiar route up to this interchange.

Abstract: When an update instruction to update “A” navigation map information and “B” navigation map information is inputted, a CPU initializes the storage area having stored therein no map information currently in use out of the two storage areas. The CPU then reads, from a CD-ROM, the latest version of the “A” navigation map information or the “B” navigation map information that corresponds to the map information currently in use, and stores it in the initialized storage area. The CPU then updates management information, starts use of the newly stored map information, initializes the storage area having stored therein the map information whose use is stopped out of the two storage areas, reads, from the CD-ROM, the latest version of the “A” navigation map information or the “B” navigation map information not currently in use, and stores it in the initialized storage area.

Abstract: An information center generates packets of route guidance information, each corresponding to a prescribed road length of a recommended route. The information center may generate major guide point information and guidance information and transmit both to a vehicular apparatus. The vehicular apparatus provides guidance only for major guide points based on the received major guide point information if it cannot receive the guidance information. According to another aspect of the invention, if the end of a route segment which was the subject of the preceding route guidance information is on an expressway or toll road, guidance information for a preliminary route from that end to an escape position ahead on the expressway or toll road is first transmitted and then information for a remaining route, that is a segment of the recommended route having the prescribed road length minus the preliminary route, is then transmitted. If communication with the information center is lost, the vehicular apparatus performs guidance for the preliminary route to an interchange, for example, of the expressway using the preliminary route guidance information.

Abstract: A vehicle navigation system realizing a discrete display of the present position of a vehicle during a period from when the vehicle reaches a predetermined distance before an intersection until the vehicle passes the intersection. Especially, in a zone a short distance before the intersection, the present vehicle position mark is fixed at the center of the displayed intersection until the travelling direction of the vehicle is changed. Thereby, even when the accuracy of monitoring of the present position is relatively low, misindication, such that the present position is displayed as if the vehicle has passed straight through the intersection in spite of not having actually reached the intersection, is avoided.

Abstract: A CPU of a navigation apparatus stores public keys to which priorities are set and which are published by an information distribution center in a public key storage section. The CPU of the navigation apparatus extracts an electronic signature of distribution data which is distributed from the information distribution center and verifies the electronic signature by using only ‘valid’ public keys among the public keys in order of the priorities. The CPU of the navigation apparatus determines that the distribution data is valid information which is distributed from the information distribution center when the electronic signature passes verification.
